Earthquakes Rattle California Every Few Minutes

They’re shaking things up. According to a new study by California-based researchers, the Golden State’s sunny southern areas are hit with a tiny earthquake about every three minutes — 10 times more often than previously known. Aided by more advanced technology, experts were able to clock formerly undetected tremors with a magnitude of 0 to 1, leading to the discovery of some 1.8 million micro-temblors between 2008 and 2017.

Why does this discovery matter? Seismologists hope the study could help detect undiscovered faults and patterns of foreshocks and earthquake swarms, potentially leading to more effective predictions.
